Power Supply Connection; Device Learning; Learning Of The Mechanical Stop Positions; Checking The Boom's Movement - Nice M3BAR Instructions And Warnings For Installation And Use

5.3 POWER SUPPLY CONNECTION

a
The power supply connections must only be made
by qualified and experienced personnel possessing
the necessary requirements and in full conformity
to the laws, regulations and standards in force.
Connect the control unit to a power line equipped with a safety
earthing system. Install a circuit breaker with a contact gap
that ensures full disconnection in the Category III overvoltage
conditions, or mount a plug and socket system.
As soon as the product is powered, a few simple checks should
be carried out:
check that the display switches on.
1.
make sure that the LEDs on the photocells (both the TX
2.
and RX) also flash; the type of flashing is irrelevant, since
it depends on other factors.
check that the device connected to the FLASH output or
3.
the LED warning light XBA7 is switched off (with factory
setting).
If the above conditions are not satisfied, immediately switch
off the power supply to the control unit and carefully check the
electrical connections.
Further useful information on searching and diagnosing faults is
included in the "Troubleshooting" paragraph.

5.4 DEVICE LEARNING

After connecting the power supply, the control unit must learn
the devices connected to the "BlueBUS" and "STOP" inputs.
m
The learning phase must be carried out even if no
device is connected to the control unit.
Start the procedure by activating parameter Set 1 (refer to the
chapter "PROGRAMMING").
The self-learning phase of the connected devices can be
repeated at any time also after the installation, for example
whenever a device must be added.
5.5 LEARNING OF THE MECHANICAL STOP
POSITIONS
Once the connected devices have been learned, the
mechanical stop positions must be learned (maximum opening
and maximum closing).
To do this:
unlock the gearmotor with the relevant key provided (refer
1.
to the "Manually unlocking and locking the gearmotor"
paragraph)
manually move the boom to about half-way (45°) and
2.
leave it stationary
lock the gearmotor
3.
4. start the level search procedure by activating parameter
Set 2 (refer to the chapter "PROGRAMMING")
while the manoeuvres are being executed, make sure that
5.
the boom's balancing lever strikes the mechanical stops of
the limit switch. If this does not occur, stop the procedure
by pressing encoder (A), adjust the mechanical stops
of the limit switch and repeat the procedure from the
beginning
a
Do not interrupt the execution of the manoeuvres: if
this occurs, the entire procedure must be repeated
from the beginning.

5.6 CHECKING THE BOOM'S MOVEMENT

Once the learning stage is complete, it is advisable to carry out
a few manoeuvres in order to verify that the boom gate moves
properly.
37
To do this:
1. press the
f
manoeuvre; check that the boom starts slowing down
before reaching the open position
press the
2.
h
manoeuvre; check that the boom starts slowing down
before reaching the closed position
during the manoeuvre, check that the LED warning light, if
3.
present, flashes alternatively on and off every 0.5 seconds
4. open and close the gate several times to make sure that
there are no points of excessive friction and that there are
no defects in the assembly or adjustments.

5.7 CONNECTING OTHER DEVICES

If the user needs to power external devices, such as a radio
receiver or the light of the key selector switch, power can be
tapped as shown in the figure.
The power supply voltage is 24Vc -30% ÷ +10% with a
maximum available current of 500mA.
